Abstract

ADP-ribosylation regulates the activity of numerous proteins involved in the DNA damage response and repair. A new study shows that telomeric DNA can be ADP-ribosylated by PARP1, and prompt removal of the ADP-ribose by TARG1 is essential to preserve telomere integrity, unveiling DNA–ADP-ribosylation as a novel player in telomere stability.

ADP-核糖基化端粒 DNA 的风险业务

ADP-核糖基化调节着许多参与DNA损伤反应和修复的蛋白质的活性。一项新的研究表明，端粒DNA可被PARP1进行ADP-核糖化，而TARG1及时清除ADP-核糖对保持端粒完整性至关重要，这揭示了DNA-ADP-核糖化是端粒稳定性的一个新角色。

期刊介绍： Nature Structural & Molecular Biology is a comprehensive platform that combines structural and molecular research. Our journal focuses on exploring the functional and mechanistic aspects of biological processes, emphasizing how molecular components collaborate to achieve a particular function. While structural data can shed light on these insights, our publication does not require them as a prerequisite.
